ABSTRACT:
A snowmobile steering ski or skis, which may be equipped with a ski liner to prevent undue drag on a snowmobile snow, includes a integral fin that enhances steering control in turning or resisting sidehill slippage of the snowmobile particularly in traversing powder or hard packed. The ski liner fin is integral, or replaceable, and extends outwardly along the outer edge and downwardly over a central portion of the ski. The fin contacts the snow on the inner side of either a flat turn, or the uphill slope of a sidehill run, because the forward end of the snowmobile ski is cambered so as to tip downwardly toward the steered direction of a turn.
